1. Cells 3.b. Compare and contrast the major components and functions of different type of cells. (DOK 2)  Differences in plant and animal cells  Structures  Different types of cells and tissues

2. Vocabulary words

3. Cell The smallest unit of an organism that carries on the functions of life

4. 2 Types of Cells Plant cell Animal cell

5. Organelle Structure in the cytoplasm of a eukaryotic cell that can act as a storage site, process energy, move materials, or manufacture substances

6. Cell Wall Rigid structure that encloses, supports, and protects the cells of plants, algae, fungi, and most bacteria ONLY IN PLANTS! Is the outermost layer of plant cells

7. Cell Membrane Protective outer covering of all cells that regulates the interaction between the cell and the environment In plant and animal cells Is the outermost layer of animal cells

9. Cytoplasm Constantly moving gelatin-like mixture inside the cell membrane that contains hereditary material Is the location of most of a cell’s life processes

10. Ribosome Small structure on which cells make their own proteins

11. Nucleus Organelle that controls all the activities of a cell Contains hereditary material made of DNA

12. Nuclear Membrane Double-layered membrane enclosing the nucleus of a cell that controls materials entering and leaving the nucleus

13. Chloroplast Green, chlorophyll-containing plant-cell organelle that captures light energy, which is used to make sugar Only in plants

14. Mitochondrion Cell organelle where food is broken down which releases energy that is stored in sugar Known as “powerhouse” of the cell Responsible for cellular respiration Has similar function in both plant and animal cells – Provides energy to both

15. Endoplasmic Reticulum Cytoplasmic organelle that moves materials around in a cell and is made up of a complex series of folded membranes Rough ER: with ribosomes Smooth ER: without ribosomes

16. Golgi Body Organelles that sort and package cellular materials and transports them within the cell or out of the cell

17. Organ Structure, such as the heart, made up of different types of tissues that all work together

18. Organ System A group of organs working together to perfom a certain function

19. Large/Central Vacuole Storage of waste and small molecules Only in plant cells

20. Lysosome Organelle present in animal cells that contain digestive enzymes responsible for breaking down proteins.

21. Tissue Group of similar cells that work together to do one job

22. Types of Cells/Tissue 1. Epithelial 2. Nerve 3. Bone 4. Blood 5. Muscle

23. Epithelial Cells Covers body surfaces and lines internal organs

24. Nerve Cells Detects information/stimuli from the environment

25. Bone Cells Store nutrients to make our bones strong enough to support our body

26. Blood Cells Carries oxygen throughout the body

27. Muscle Cells Attaches to bone and helps control movement

28. Selectively permeable When the cell membrane allows some molecules to enter the cell but prevents other substances from entering the cell
